SOLIDWORKS Frequency Analysis

Quickly and efficiently investigate the natural frequencies of a design—with and without loads and boundary conditions—with easy-to-use SOLIDWORKS Simulation. Ensure that the natural modes of vibration are away from environmental forcing frequencies, indicating that the design will meet the required service life.

Tightly integrated with SOLIDWORKS CAD, frequency analysis using SOLIDWORKS Simulation can be a regular part of your design process, reducing the need for costly prototypes, eliminating rework and delays, and saving time and development costs.

Frequency Analysis Overview

Understanding the natural frequency is important in predicting possible failure modes or the types of analysis required to best understand performance. Every design has its preferred frequencies of vibration, called resonant frequencies, and each such frequency is characterized by a specific shape (or mode) of vibration.

Frequency analysis with SOLIDWORKS Simulation uses an Eigen value approach to determine the natural modes of vibration for any geometry. If a design’s natural modes and its expected service vibration environment are closely matched, a harmonic resonance may occur and lead to excessive loads which will result in failure.

By understanding the design’s natural modes of vibration, you can carry out preventative measures, such as changes in material, component sections, mass dampers, and so forth, so that component natural frequencies do not coincide with the frequency of the loading environment. This results in a design that would not only perform as desired, but also have a longer service life.

To push the natural frequency of a design out of the critical range, you can:

  • Change geometry
  • Change materials (resonant frequencies are directly proportional to the materials [Young’s (elastic) modulus]
  • Change the characteristics of the shock isolators
  • Strategically place mass elements
